Hybrid Repair of Ascending Aortic Pseudoaneurysm

For ascending aortic pseudoaneurysms with a large aortic entry site and thrombus burden, temporary stent-graft placement at induction of circulatory arrest can prevent thrombotic complication.

Acutely ruptured basilar artery bifurcation aneurysm, treated with simultaneous Cascade and Comaneci temporary-assisted coiling

Temporary stent-assisted coiling is an eligible approach for the treatment of acutely ruptured complex cerebral aneurysms. Improved material properties and industrial advances in braiding technology have led to the introduction of new stent-like devices to augment endovascular coil embolization. Such technology includes the Cascade and Comaneci neck-bridging devices. Both devices are manually controlled, non-occlusive and fully retrievable neck-bridging temporary implants. The braided nature and the ultra-thin wire, compliant structure of their bridging meshes helps maintain target vessel patency during coil embolization. In this video (video 1) we demonstrate the straightforward combination of two temporary neck-bridging devices for the embolization of an acutely ruptured aneurysm of the basilar artery. Technical success and complete embolization of the aneurysm were recorded at the final angiography. In this technical video we discuss the technical nuances of the Comaneci and Cascade coil embolization.Video 1

Using stent retriever pRESET during embolization of intracranial aneurisms

The study objective is to present the results of applying stent retriever pRESET as assistance device in embolization of brain aneurysm.Materials and methods. Between January 2017 and May 2018, were threated 10 patients with brain aneurism using temporary stent-assistant method. The average aged was 41. Asymptomatic aneurysmal disease was observed in five patients, two patients were operated on in the acute period of subarachnoid hemorrhage, in two cases temporary stent assistance was used for pre-embolization of previously operated aneurysms. Temporary stent assistance was performed using a stent retriever pRESET (Phenox, Germany).Results. The technical success of the intervention was 100 %. Total embolization of aneurysms was achieved in seven patients, in three patients subtotal embolization was observed. All observations had positive neurological outcomes on discharge.Conclusion. Temporary stent assistance using a stent retriever pRESET is an additional option for endovascular treatment of brain aneurysms.Conflict of interest.
